LOCK.

i SPECIFICATION forming part of Letters. Patent No. 268,692, datedDecember 5, 1882.

' Application filed May 17,1882. Model.} 7 i l T all whom t't mayconcern:

Be it known that I, ADOLPH KLAUNIG, of Newark, in the county ofEssexiand State of New Jersey, have invented a new and usefulImprovement in Locks, of which the following is a'specification.

My invention relates to self-locking trunk or drawer locks in which whenthe key has been turned in unlocking it may be taken out and the trunk,&c., be opened at any time thereafter, and the closing of the trunk ordrawer will lock it; and it consists in the devices substantially ashereinafter set forth.

Figure 1 is a rear side view. Fig. 2 is the same, with the plateremoved, showing the look when locked. Fig. 3 is the same unlocked. Fig.4 is the same, showing a modification adapting it for use as adrawer-lock. Fig. 5 is a detailed View of a catch as used in connectionwith a drawer-lock.

In my construction I attach to the plate A four stationary pins, B C DE. On the bolt H are two pins, F G. The pins D E are used as guides forthe bolt, the former being on the lower edge of it and the latterWorking in the slot I. The tumblers a are hung on the pin D. There aretwo or more tumblers, fitting into difierent wards of the key K, makingit more difficult to open the look without the regular key. In opening,the key is placed on the stem or pin 0 in Fig. 2, and the bolt is movedto the right. In this movement a spring-lever, L, hung to the bolt onthe pin G, is also carried to the right, and the rounded end strikes thecatch m, and rises up into the slot n in the catch, (seenin Fig. 5.) Onthe pin G is also hung a shouldered stop, 1?, acted on by the spring Q,and whenthe bolt is carried to the right, so that the catches S of saidbolt are out of the catch on, this stop will drop down, and the shoulderwill catch against the pin E- and hold the bolt unlocked until the coverhas been lifted up, so that after the bolt has been slid in unlockingthe key maybe taken out, and the locking again is prevented by the stopP; but the raising of the cover, carrying up the catches m,'carries upalso the end of the lever L, resting inth'e right-hand catch, until thecatch is removed or passes the end of the lever. Then the spring 0,acting on the other end of the lever, restores the lever to its formerposition. Then when the cover is again pressed down the catch mwillpress down the, end of the lever, which will throw up the oppositeend of this lever and throw up the stop,.and allow the bolt again toengage the catch m by the action of the spring T, as seen in Fig. 2.

The provision for using the same look for a drawer is in having, asshown in Fig. 4:, a side catches m, when the drawer is slid in on aplane with the top of the'lock,will engage the catches S of the boltfrom the side instead of, as in a trunk, from the top. The catch m inFig. 5 shows a beveled side to slide on the patch.

I claim- The bolt H, sliding on the guide-pins D E, lever L, stop P,hung on the pin G, and the springs O and Q, in combination with a key,K, and catches m, substantially as and for the purpose specified.
